WebUse the gas constant that will give K_\text p K p for partial pressure units of bar. To solve this problem, we can use the relationship between the two equilibrium constants: K_\text p = K_\text c (\text {RT})^ {\Delta \text n} … WebIn contrast if the pressure is decreased, then the equilibrium will shift forward. However, the pressure we apply must have effect on the partial pressure of the reactants and/or products. If we increase the pressure by adding an irrelevant gas (e.g. Helium) under constant volume, then the equilibrium will not shift.
